Or not created directly, but just some law of the universe that cheating isekai'd folk get loyal, braindead groupies that exist solely for them, but only as long as they're undefeated as a way to parody all the slop with instant harems.
Far as anyone's been able to tell in the past, it's just the artist deciding to overemphasize the difference between Sylphy and Dyne, the water spirit, because you'll notice Sylphy didn't really start shrinking until after the boob spirit that is Dyne was introduced.
